Spinel -- Ruby AOT Compiler

Spinel compiles Ruby source code into standalone native executables. It performs whole-program type inference and generates optimized C code, achieving significant speedups over CRuby.

Spinel is self-hosting : the compiler backend is written in Ruby and compiles itself into a native binary.

How It Works

Ruby (.rb) | v spinel_parse Parse with Prism (libprism), serialize AST | (C binary, or CRuby + Prism gem as fallback) v AST text file | v spinel_codegen Type inference + C code generation | (self-hosted native binary) v C source (.c) | v cc -O2 -Ilib -lm Standard C compiler + runtime header | v Native binary Standalone, no runtime dependencies

Quick Start

<div dir="auto" data-snippet-clipboard-copy-content="# Fetch libprism sources (from the prism gem on rubygems.org): make deps

# Build everything: make

# Write a Ruby program: cat > hello.rb <<'RUBY' def fib(n) if n < 2 n else fib(n - 1) + fib(n - 2) end end

puts fib(34) RUBY

# Compile and run: ./spinel hello.rb ./hello #…
